Drainage device for abdominal operation wound

Abstract

The invention provides an abdominal operation wound drainage device which comprises a split drainage tube and a negative pressure ball, the split drainage tube is composed of a hose and a drainage apparatus, the drainage apparatus is inserted into one end of the hose, and the other end of the hose is connected with the negative pressure ball; the drainage device comprises an upper arc-shaped pressing piece, a lower arc-shaped pressing piece and an X-shaped supporting piece connected between the two arc-shaped pressing pieces, and two bottom feet on the upper side and the lower side of the X-shaped supporting piece are fixedly connected with the upper arc-shaped pressing piece and the lower arc-shaped pressing piece respectively. A row of drainage holes are distributed in the upper arc-shaped pressing piece in the length direction, and long-strip-shaped drainage grooves distributed in the length direction are formed in the lower arc-shaped pressing piece. The included angle alpha 1 of the two sides of the X-shaped supporting piece ranges from 50 degrees to 70 degrees, the two sides of the upper arc-shaped pressing piece are flush with bottom feet of the X-shaped supporting piece, and distances are reserved between the left side and the right side of the lower arc-shaped pressing piece and the bottom feet of the X-shaped supporting piece. The abdominal operation wound drainage tube can well conduct drainage on an abdominal operation wound, and compared with a traditional cross-shaped drainage tube, the abdominal operation wound drainage tube is beneficial to wound healing.

Description

technical field [0001] The invention relates to drainage of abdominal wounds, in particular to a drainage device for abdominal surgical wounds. Background technique [0002] Drainage tube is a medical device used for clinical surgical drainage to guide pus, blood, and liquid accumulated between human tissues or body cavities to the outside of the body to prevent postoperative infection and promote wound healing. There are many types of surgical drainage tubes used clinically, some are used for catheterization, some are used for wounds, and they are used in the chest cavity, brain cavity, gastrointestinal tract, and biliary tract. The purpose of peritoneal drainage is to guide the pus, blood, and fluid accumulated in the body cavity to the outside of the body to prevent postoperative infection and affect wound healing.

AI Technical Summary

Problems solved by technology

[0003] There is currently no mature abdominal wound drainage device clinically. Most of them are ordinary drainage tubes with side holes, that is, a drainage hole is directly set at one end of the drainage tube for drainage. However, the drainage effect is not ideal in actual use, and the drainage tube is easy to block.
